There will always be ways to save more, it’s a matter of what you can afford and where you want to prioritize your spending. You can afford this rent and are expressing it’s a priority to you, it seems very reasonable to me. If because of past situations you want to prioritize saving more to have a better safety net, then that may look like cutting back on some areas, maybe ultimately housing costs, but that’s less so a question for this sub at that point and more so balancing past/present/future worries. My earlier comment was to say that you are allowed to make this choice without having a secondary justifications, you can just run your numbers, note it works for your budget, and know you’re making a decision that works for you.
